means torboiling liquids, whereby all the heat z is utilized, an d, furthermore, to provide means whereby the contents of the boiler are kept.v

well agitated during the operation ot boilin The invention consists in a certain novel construction and arrangement of devices, fully set forth hereinafter in connection with the accompanying drawings, wherein Figure l a perspective view ol the improved. heater. Fig. i is a vertical central sectional view ther-coli'. Fig. 3 is a sectional lview of the boiler, to show the agitator and the devices for securing the cover in place. Fig. L is adetail perspective view of the removable cap. Fig. 5 is adetail sectional view oli' a portion of the heating device.

Referring to the drawings, A designates a truck or frame mounted on rollers, which is provided with uprights or standards B B, having bearings or forks l) l) at their upper ends; and C designates the heating device, which is provided with the reservoir c and the burn ers c c', arranged between the said uprights or standards.

The boiler D,which is arranged between the uprights or standards over the burners, is provided with the lateral trnnnicnis e e, mounted in the bearings or forks b b, and the crank E, affixed to one of the trunnions, whereby the boiler maybe rotated between the uprights or standards in order to bring either end over the flame of the burners. rlhe boiler is provided with a concave bottom, d, in order to concentrate and hold the heat, and the cover F, which lits on the upper end of the boiler, is similarly coneaved, and is provided with the ventbpening f, beneath which is arranged the ballvalve G, held adjacent to the opening by the basket g. Then the boileris reversed, this valve drops by gravity and closes the vent-opening, thereby preventing the con tents of the boiler from escaping thereheating device.

through. An elastic paeki ng, o l rubber, cork, or its equivalent, is arranged between the cover and the upper edge of the boiler in order to form a water-tight joint.

il II represent ears, which are z "anged on 'the inner side ol the boiler near Vts upper end, and the transverse bar l (which removable from the boiler) is provided with notches l' i in its ends, which are engaged with the said ears to Ahold the bars in a transverse horizontal position in the boiler. rllhis bai-is provided at Aits center willi the vertical threaded stud or arm K, which. extends through a central aperture in the cover, and is engaged by the thumb-nut L, whereby the cover may be forced down tightly on the elastic packing.

M represents a rmnovable cap, which is litted on the lower end of the boiler, and is provided with a perda-ated bottoni, in, having apertures N N to receive the burners of the This cap is supported on the burners, and its bottom is removed some distance from the bottom of the boiler to form a combustion-chamber, O, in which the heat of the burners is conined and concentrated against the bottom of the boiler. rllhe perforations in the bottom in allow a free circulation of air to support combustion. The sides ot' the cap consist of the semi-cylindrical sec` tions m m,which are hinged at the centers oi their lower ends to the edges of the perforated bottom, and are held in contact at their adjacent side edges by the hooks m2 fm2 engaging suitable keepers, mn m3. It will be understood that this cap is allowed to remain on the lower end of the boiler while the contents of the latter are heating; but when it is desired to rotate the boiler the cap must be removed, either by sliding it up until the apertures N N are disengaged from the burners and then swinging the boiler laterally a sufficient distance to allow the cap to be slipped oit, or by disengaging the hooks m2 and spreading the sides of the cap.

l? represents an agitator which is arranged in the boiler, and it consists of the'lower rounded or curved plate, Q, provided with a central aperture, q, and the perforated tube roo q', arranged over the said aperture, and the upper rounded or curved plate, R, provided with a central aperturen', and the perforated tube r., arranged under the-said aperture and fitting within the tube q. The lower plate is convexed upward at its center to be out of contact with the bottom of the boiler, and the upper plate is convexed downward at its center to be out of contact with the cover, and both plates are provided with perforations S. As the boiler is rotated on its trunnions, this agitator moves vfrom one end thereof to the other, the liquid beingl forced to pass through the perforations in the tubes and the plates, and thereby kept well agitated.

This dev-ice may be used for various purposes where it is desired to heat rapidly and thoroughly and maintain the contents of the boiler in a state of agitation. It may be used as a clothes-boiler, vthe fabrics being placed in the boiler around the perforated tubes and between the perforated plates. It willbe seen that the clothes will be kept out of contact with the heated ends of boiler, and the water will be forced and drawn through them during the rotation of the boiler, thereby rapidly and thoroughly cleansing the same.

The boiler may be used for boiling tar, oil,

soappaste, andother similar substan ces which mustbe heated to a high degree and should be kept in motion to prevent burning, as maplesirup, &c. It will also be observed that the contents of the boiler may be readily pouredl therefrom after the cover is removed .by simply inclining it by means of the crank.

The boiler -may be made lof any suitable material-as copper, brass, galvanized iron, t-in, &c.-.and the truck -may be made either of iron tubing, wood, metal, or other similar material. I prefer to use oil `orgasoline as the fuel for .the heating device, although coalg'as,'natural gas, or any suitable material may be used.

VThe .heating device-C is secured in place by iianges, which are bent over upon and partly around the cross-'bars or cross-pipes of the frame A, the said flanges being preferably formed integral with the reservoir of the heating device.

Having thus described my invention, I claiml.
